I have a problem, I have an angel that I've had for about 5 months now and I got to looking at hin and on one side if him there are four pinsize knots on him, does anyone seem to know what this might be? I looked on the web but found nothing. T guy at the LFS said to throw it in the toilet because it had parasites and would infect the other fish. I can't hardly do that because thats just the way I am. His mouth does'nt shut all the way and he quit eating as of yesterday. What to do?
